Add support for multiple filters per variable. re: https://github.com/Unidata/netcdf-c/issues/1584 Support has been added for multiple filters per variable. This affects a number of components in netcdf. The new APIs are documented in NUG/filters.md. The primary changes are: * A set of new functions are provided (see __include/netcdf_filter.h__). - Obtain a list of the filters associated with a variable - Obtain the parameters for a specific filter. * The existing __nc_inq_var_filter__ function now returns info about the first defined filter. * The utilities (ncgen, ncdump, and nccopy) now support an extended format for specifying a sequence of filters. The general form is __<filter>|<filter>..._. * The ncdump **_Filter** attribute now dumps a list of all the filters associated with a variable using the above new format. * Filter specifications can now use a filter name instead of number for filters known to the netcdf library, which in turn is taken from the HDF5 filter registration page. * New errors are defined: NC_EFILTER and NC_ENOFILTER. The latter is returned if an attempt is made to access an unknown filter. * Internally, the dispatch table has been extended to add a function to handle all of the filter functions. * New, filter-related, tests were added to nc_test4. * A new plugin was added to the plugins directory to help with testing. Notes: 1. The shuffle and fletcher32 filters are not part of the multifilter system. Misc. changes: 1. A debug module was added to libhdf5 to help catch error locations.

Fix reclamation of the ->format_XXX_info fields nc4internal.c contains code to free the format_XXX_info fields. Since these are format specific, this code was moved to the dispatch code (libhdf5 and libhdf4 in the current case). Additionally, there are some fields in nc4internal.h (e.g. dimscale fields) that are specific to HDF5 and have been moved to the corresponding HDF5 data structures and code. Misc. other changes: 1. NC_VAR_INFO_T->hdf5_name renamed to alt_name to avoid implying it is necessarily HDF5 specific. 2. prefix NC_FILE_INFO_T with an instance of NC_OBJ for consistency. this also requires wrapping move_in_NCList() to keep hdr.id consistent.
